TURNBACK CANOPY-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 772,174, dated tob r 11, 1904:. Application filed February 7, 1 903. Serial No! 142,311. (No model.)

To all whom it may concern:

Be it known that l, ISAAC E. PALMER, a citizen of the United States, and a resident of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and useful Turnback Canopy-Support, of which the following is a specification.

My invention relates to a turnback canopysupport in which the canopy supporting frame has a resilient connection with the supporting-bracket and in which the supportingbracket is made adjustable to suit .difierent sizes of bed-posts.

In the accompanying drawings, Figure 1 is aview of one of the supporting-brackets and supporting-arms in side elevation,showing the position of the supporting-bracket with respect to a post of the bedstead as in use. Fig. 2 is an enlarged view of a portion of the same in side elevation, partly in section, showing the manner of uniting the supporting-arm with the resilient section. Fig.3 is an enlarged view, in front edge elevation,of the adjustingdrum for removably connecting the canopysupporting arm and resilient section with the supporting-bracket. Fig. 4 is a view of the same in side elevation on the side reverse from that shown in Fig. 1. Fig. 5 is aview in side elevation of one of the sections of the springadjusting hub. Fig. 6 is a similar view of the other section of said hub. Fig. 7 shows the supporting-bracket, on a larger scale, in its position fast on the post, the view being taken in elevation from the outer side of the post, similar to that shown in Fig. 1. Fig. 8 is a horizontal section through the post, showing the supporting-bracket in top plan. Fig. 9 is a horizontal section taken through the bracket, the socket-piece of the bracket being removed; and Fig. 10 is a View of the socket-piece of the bracket in face elevation.

The canopy-supporting device, illustrated as stated above, forms one of a pair of these devices which are commonly used for supporting a canopy over a bed, the two companion pieces being identical in structure save only that they are arranged right and left, so that they may be applied to the front and back of the bed symmetrically.

The supporting-bracket is composed of two L-shaped sliding sections 1 and 2, (see Fig. 9,) one branch of the section 2 being arranged to slide along the back of one branch of the section 1 in a loop 3 to increase or diminish the length of the bracket to accommodate itself to the bed-post et. The back of the section 2 is channeled, as shown at 5, (see Fig. 7,) and in this channel there is seated a key 6, made in the shape of an elongated chain-link, one of its branches extending outside of the loop 3 and the other within the loop 3 between it and the back of the section 2. This inner part 7 of the key 6 is made tapered, as clearly shown in Fig. 9, so that the key may he slid in a direction to tightly wedge or look the section 2 and section 1 and so that it may be slid in the opposite direction to loosen the section 2 from the section 1 and permit the two sections to be adjusted with respect to each other. The feature of the key 6 is that it is not liable to become lost or misplaced, for the reason that it is permanently held in the loop 3. The other branch of the section 1 of the bracket is provided atits free end with a depending pintle 8, having a side'9 flattened for preventing the pintle from turning in its socket. A socket-platelO, having a socket 11 for the reception of the pintle 8, is provided with perforations 12 and 13, through which it is securely fixed to the post by some suitable fastening, as shown in Fig. 7 The other branch of the section 2 of the bracket is provided with a socket 14, angular in cross-section, for receiving the pintle on theframe of the adjustingdrum,as follows: The adjust-. ing-drum for supporting the resilient section of the canopy-supporting arm is composed of a plateor disk 15,'provided with a central hub or drum 16 of a length corresponding to the width of the resilient section of the canopy-supporting arm, the said hub or drum 16 being provided with a slit 17, extending.

through. it, preferably in. curved form, as shown, for receiving and retaining the lower end of the resilient section. The said plate 15 is also provided with a series of perforations 18 near its periphery for adjusting the resilient section, as will hereinafter appear. The said adjusting-drum further consists of a disk or plate 19, provided at its center with a screw-threaded pin or stud 20, intended to pass through a perforation 21 in the center of the hub or drum 16 on the section 15, and a nut 22, (see Fig. 3,) working on the threaded end of the screw 20, serves to clamp the plate firmly to the plate 19, with the free end of the hub or drum 16 bearing against the inner face of the plate 19. The plate 19 has'cast integral therewith a pintle 23, angular in cross-section to correspond to the socket 14c in the bracket-section 2, and there is also formed, in connection with the casting at the head of the pintle 23, a stud 2 1 in position to enter some one of the perforations 18 in the plate 15 to holdthe latter in the desired rotary adjustment with respect to the plate 19.

The resilient section which carries the canopy-supporting arm proper is composed of one or more flat springs, in the present instance two, (denoted, respectively, by and 26.) These are tightly wedged in the slit 17 in the hub 16, as clearly shown in Fig. 5, and extend upwardly between the plates 15 and 19. The upper end of the spring 25 has permanently fixedthereto a coupling-piece 27, the end of the spring 25 being in the present instance .snugly impinged in a socket 28 in said coupling-piece, as clearly shown in Fig. 2. The coupling-piece 27 has a loop 29 at its upper end and a loop 30 at its lower end. The springs 25 and 26 both pass through the loop 30, the spring 26 being free to slide along the face of the spring 25 as the canopy-supporting arm is moved forwardly or allowed to spring backwardly.

The canopy-supporting arm is denoted by 31. It passes freely through the loop 29 and is provided at its lower end with a couplingpiece 32, having a loop 33, which loosely embraces the springs 25 26 below the loop 30 on the coupling-piece 27. This permits the arm 31 to slide upwardly and downwardly along the springs 25 and 26 to adjust the arm to a greater or lesser length, as may be required, and to hold the said arm 31 in the desired adjustment I fit the loop 29 with a key 34 quite similar to the key 6, already shown and described.

For the purpose of supporting the canopy at the head of the bed I' provide an upright standard 35, (see Fig. &,) which may be locked in the desired vertical adjustment of the outer face of the plate 19. In thepresent instance I have shown the outer face of said plate 19 provided with a central loop 36 and bearinglugs 37 and 38, one above and the other be- -low the said loop 36, the arm passing through the loop and bearing against the lugs 37 and 38 and locked in position by means of a non-losable key 39 quite similar to the key 6, before described.

In operation the arm 31, carrying the canopy, is bent over toward the foot of the bed, the springs 25 and 26 yielding to permit this movement and their tension serving to return the arm 31 to a vertical position whenever it is desired to throw the canopy back out of use. During this movement the spring 25 is reinforced by the spring 26, the latter, as before stated, being free to adjust itself along the face of the spring 25 as the latter is bent or allowed to straighten. Whenever the spring becomes too weak either for the purpose of supporting the canopy or returning it to its upright position, either because of a heavier canopy being used or because of the spring losing some of its elasticity, the spring may be set farther back and its elasticity for supporting purposes thereby [increased by simply turning the plate 15 one or more steps, determined by the distances between successive holes 18, and securing it in its adjusted position.

The structure as above set forth is a simple one and capable of adjustment to a great variety of sizes of bed-posts, lengths of bedsteads, and heights to which the canopy may be adjusted.

It is obvious that a single spring, the thickness of the two springs 25 26, for instance, might be utilized in the place of the two and that a spring composed of more than two leaves might be used in the same manner as the two hereinabove described.

What I claim is- 1. In a canopy-support including sections adjustable with respect to one another and the loop in connection with one of said sections, of a locking-key embracing said loop and permanently secured thereto, said key being arranged to wedge between the wall of the loop and one of the sections to lock them in position.

2. In a canopy support, a supportingbracket composed of two L-shaped sections, one of the sections being provided with a socket and the other of the sections being pro vided with a pintle, one of the sections being further provided with a loop for receiving the other section in sliding adjustment and a locking-key consisting of a loop-shaped link permanently attached to the loop and arranged to wedge between the loop and the back of one of the bracket-sections to lock the sections in position.

3. In a canopy support, a supportingbracket composed of sections arranged to slide with respect to one another, a key for locking the sections in different adjustments one of the sections being provided with an angular socket and the other with an angular pintle and a socket-piece provided with an angular socket for the reception of the angular pintle on the bracket-section.
